From the Sector

At this year’s JEC World, the largest trade fair for composites held from March 3-5, 2020 in Paris, SGL Carbon will focus on the topic of serial production for the automotive, aerospace and industrial sectors. The key is customized solutions with individual component designs combined with tailored materials and production processes ready for large scale production. Under the motto “The Solution Provider,” the company will present selective innovative component solutions from all three areas in Hall 6, Booth D25. Furthermore, as an example for industrial applications, SGL Carbon will showcase at the JEC world a crossbeam made of carbon fiber reinforced plastics (CFRP) used in automated Schuler press lines.

•    Composite battery enclosures for e-mobility
•    Flexible new leaf spring generation for rear axles
•    Innovative component designs for passenger airplanes, helicopters and air taxis
•    Extremely lightweight and stable transfer beam for mechanical engineering

Selective applications with focus on serial production
In the field of automotive applications, SGL Carbon will present at the JEC World composite battery enclosures as a promising new application driven by increasing demand for electric vehicles and the resulting new flexible chassis platforms. The company demonstrates a prototype of a battery enclosure based on carbon fibers. However, hybrid composites with a mixture of glass and carbon fibers are also possible.

In the aerospace sector, SGL Carbon is also expanding its portfolio of realized projects and expertise relying on the trend to use more efficient materials and processes in this industry too.
In the area of primary structure components, the company will present a demo exhibit for the door frame of a passenger airplane realized in collaboration with external partners and based on 50k carbon fiber from the SGL Carbon, which is suitable for serial production.

Live simulations and intense exchange at the booth
Visitors can experience live how their ideas can be implemented both sustainably and cost-effectively in composites thanks to simulations. Experts from the company’s own Lightweight and Application Center demonstrate the path from the concept to virtual prototypes using simulation software, with the result visible either to the entire audience or just individual visitors. To prepare, interested parties can contact the team now at the following link: https://www.sglcarbon.com/anmeldung-jec.

On March 4, 2020, the SGL Carbon stand will host its traditional get-together for customers and friends starting at 4 p.m. – no registration necessary.
 

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

At JEC World 2020, MECELEC COMPOSITES is a finalist of the JEC Innovation Awards in the Design & Furniture category. The Group announces the launch of a new sustainable development application on the urban design market. MECELEC COMPOSITES designed the first mass-produced flax fibre roofs for the 550 Morris columns installed by JCDecaux in Paris. “This is the first application of flax fibre BMC for mass production. The new solution combines all the advantages of composite materials, lightness and strength, with stringent environmental requirements and is adapted to the safety constraints of this kind of street furniture,” says Bénédicte Durand, Chief Executive Officer at MECELEC COMPOSITES.

A COMPOSITE ROOF THAT IS BOTH INNOVATIVE AND GREEN
The dome of the Morris columns is composed of 23 different parts, 14 of which are made from composite materials. To design the roof, MECELEC COMPOSITES developed a new RTM complex and a new BMC material, that is reinforced exclusively with a flax mat. “Today it is the only BMC with a 100% flax fibre reinforcement, which uses a partially recycled ABS resin. It was created specifically for this project and we had to work on the processes in order to adapt them to this new material,” explains Bertrand Vieille, Head of sales.
In the design, MECELEC COMPOSITES replaced the bonding process with a time-saving mechanical assembly process using an invisible fixing system.

AN ECO-FRIENDLY APPLICATION IN LINE WITH THE GROUP’S ECO-DESIGN CSR APPROACH
MECELEC COMPOSITES creates scalable, sustainable and environmentally-friendly street furniture. The Group is committed to developing a sustainable production process and reuses all its waste materials. MECELEC COMPOSITES R&D laboratory promotes eco-design with a process of characterisation and mechanical sizing of parts. “For this project, we imagined, created, produced and delivered a mass-produced composite application with a low environmental impact within less than a year. At the end of its lifecycle, the product completely breaks down, leaving no fibre residue,” Bénédicte Durand concludes.
